without knowledge of plate tectonics

seismograph and its relationship to volcanoes

Apr 30, 1842

in 1942 the seismograph was invented by James David Forbes. It is known that most volcanoes are on the boundaries of tectonic plates, magma comes from there. Earthquake can be detected before the eruption. Whitout dicovery of tectonic plates we couldn't use the seismograph to prevent eruptions

beginnings of seismology

Apr 30, 1910

In 1910 Harry Reid and Andrew Lawson, proposed a model of elastic rebound by the deformation of tectonic faults that explained the San Francisco earthquake in 1906. Would not know what causes earthquakes

continental drift

Apr 30, 1915

This year the theory of continental drift was developed by Alfred Wegener. We would not know that the continents moved for millions of years and still do

species movement

Apr 30, 1915

if we did not know about plate tectonics, we would not know that there were northern species that migrated south and viceverza, by the emergence of the Isthmus of Panama.

tsunami warning network

Apr 30, 1946

we can not prevent tsunamis if we ignore its relation to earthquakes. Also we wouldn't know it relates to the movement of tectonic plates. In 1946 was created the tsunami warning network

Orogenesis

Apr 30, 1960

acceptance of the theory of the movement of tectonic plates allowed the explanation of orogeny to the lifting of the mountains. We wouldn't how montains are formed

ocean ridges

Apr 30, 1960

between 1950 and 1969, marine geologists found via sonar, between the North Atlantic and Pacific the existence of a series of mountain ranges formed by plate tectonics. We wouldn't know how it is formed

Isthmus of Panama

Apr 30, 2014

probably, if we didn't know about plate tectonics, we would think that the Isthmus of Panama is formed by sediment accumulation and not by the action of the plates

Pacific Ring of Fire

Apr 30, 2014

if we did not know of tectonic plates probably would not know that there is a process called subduction and is responsible of formation of the Pacific Ring of Fire

Mediterranean sea

Apr 30, 2014

probably, if we did not know about plate tectonics, we wouldn't know that the Mediterranean Sea is interior because the plates closed its passage
